比較不同顯微組織條件下TC4ELI合金的斷裂韌性，并從斷裂韌性本質(zhì)定義的角度分析影響材料斷裂韌性的因素。不同狀態(tài)下TC4ELI合金斷裂韌性值表明，片層組織具有較高的斷裂韌性，且斷裂韌性大體上隨屈服強度的升高而降低。從疲勞裂紋尖端塑性區(qū)的角度闡述了影響材料斷裂韌性的因素。

Fracture toughness KIC?of TC4ELI alloys with different microstructures was tested, and the essential definition of KIC?was introduced to explain the influence of microstructure on KIC. The results show that lamellar microstructure has high KIC?value, and the KIC?value increases with the decreasing of yield stress. Finally the crack tip plastic zone CTPZ was introduced to interpret the variations of KIC.
